Lei Pingan in the interrogation room had actually been filled with questions since he was taken into custody at the terminal.
How did the investigation team find him?
How did you determine that he was the murderer?
Normally, if the investigation team is weak, they should not be able to find the murderer.
Even if there are capable people in the investigation team, they should have followed his design and found Zheng Yuanqiao based on the shoe prints, arc shape and modus operandi!
These three, one is key physical evidence, one is logical evidence, and one is reasonable speculation, all point to the same person.
In any case, it is enough to confirm that this person is the murderer.
What's more, there are doubts that Zheng Yuanqiao himself has mental problems caused by excessive stress.
With all these combined, according to Lei Ping'an's plan, it was impossible for Zheng Yuanqiao to escape punishment.
After catching him, the whole case should be over.
Lei Ping'an believed that his only weakness was that the victim of the sixth case was actually his younger brother Wu Linjie, not the real Lei Ping'an.
But based on Lei Ping'an's work experience, it is even less likely that anyone would discover this.
Because DNA identification usually only uses STR analysis, it is impossible to distinguish identical twins.
More advanced technologies such as SNP analysis are extremely expensive and will only be used in extremely special circumstances and upon application.
But Lei Ping'an's parents divorced decades ago.
The fact that he has a twin brother is not mentioned in his personal file.
In addition, Wu Linjie and his son are biological father and son, and their DNA matches.
In this case, even if a DNA identity specialist is extremely bored, he or she cannot apply to the higher authorities to use higher-level identification technology.
Because there is absolutely no need!
So, Lei Ping'an racked his brains but couldn't figure it out.
His plan for committing the crime and his plan for escaping were flawless, so why was he caught in the end?
After hearing Lei Ping'an's question, the interrogator informed him of the process of identifying him as a criminal after consulting Shao Ming outside through the headset.
Of course, it was impossible to tell him the details.
He was only told that the task force used body measurement to confirm that Zheng Yuanqiao was not the murderer.
It was also confirmed that the deceased in the sixth case was not Lei Ping'an, but Wu Linjie.
Naturally, it can be confirmed that "Wu Linjie" is actually Lei Ping'an.
"Anthropometry?"
Lei Ping'an's face was full of surprise and doubt.
It took him a while to remember what this technique meant.
Therefore, it is even more shocking.
Throughout the crime plan, he thought of all the latest criminal investigation techniques and made perfect evasions.
But I didn't expect that I would eventually be defeated by such an ancient technology.
“That’s not right!
As far as I know, anthropometry has been obsolete for how many years?
Not only is no one in Dajing using this technology, no one in the entire country of China is using this technology."
As a former investigator, Lei Ping'an is certain of this.
Before, he often went out to attend technical seminars.
Many of the latest crime-solving technologies and their latest applications will be discussed at the meeting.
But for decades, he has never heard of anthropometry making a comeback.
This is a technology that has long been swept into the dust of history.
At most, the gait characteristics that have emerged in recent years use a similar theoretical basis as anthropometry.
Beyond that, there are simply no more applications.
There are no technical personnel who would have nothing better to do than learn this obsolete technology.
Doubtfully, Lei Ping'an wondered if the interrogator was deceiving him.
However, he suddenly thought of someone and was stunned for a moment:
"Wait, Shen Ting?"
He had heard of Shen Ting before he was suspended.
Later, I heard about Chen Ting many times from Zheng Yuanqiao.
I know that he is very good at solving cases and has mastered many criminal investigation techniques.
For example, palynology, crime profiling, etc.
And each technology has reached a very high level.
Some even surpass the highest level of technical personnel in China.
Wu Linjie's body was discovered too early, which disrupted Lei Ping'an's crime plan and made him want to end the case as soon as possible. It seemed that it was Shen Ting's "credit"!
Moreover, he was promoted by Zheng Yuanqiao to be a consultant, so it is reasonable for him to find a way to exonerate Zheng Yuanqiao.
Lei Pingan widened his eyes, feeling a little unbelievable:
“Is it Chen Ting?
He used the body measurement to lock onto me, right?"
The interrogator was stunned for a moment. He didn't expect Lei Ping'an to be so smart and guess so accurately.
However, it involves specific investigators, especially Shen Ting, who played a core role in solving the case.
Naturally, the interrogator could not tell Lei Ping'an.
Although he has been arrested and it seems that there is no chance of revenge, he still has the opportunity to communicate with the outside world.
So naturally we have to be prepared for any eventuality!
The interrogator has finished his work and left the interrogation room.
Lei Ping'an had already figured out the answer from the interrogator's expression.
He slumped in his chair and couldn't help but smile bitterly.
Zheng Yuanqiao was framed by his plan, which he thought was perfect.
But he was saved by the consultant promoted by Zheng Yuanqiao.
Perhaps, this is the cycle of cause and effect!
"Next time, if there is another chance, I must be more careful."
…
"Advisor Shen, let's go to the party tonight!"
Hearing Shao Ming's voice, Shen Ting, who was thinking about the last two doubts, was stunned for a moment:
"Ah? Are we getting together now?
